Product Description:
The MKD025B-144-GP0-KN is produced by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. It serves as a compact servo actuator for industrial automation, converting regulated drive current into precise rotary motion for indexing tables, small gantries, and auxiliary machine axes.
At standstill the motor can deliver 0.9 Nm of continuous torque, a value sized for light-duty loads that must hold position without overheating. A front-face 54 mm flange establishes the bolt pattern for mounting to gearboxes or frames, while the 40 mm centering diameter aligns the stator housing with the driven equipment to maintain concentricity. The shaft exits with a shaft with keyway so torque is transferred by positive mechanical engagement rather than friction alone. Internally, three-phase windings follow code 144, which defines the conductor gauge and number of turns and therefore fixes the voltage constant and rated current for compatible drive controllers.
Cabling enters through a connection box that simplifies field wiring and provides strain relief, and all power and feedback terminations are oriented on Side B so panel designers can route harnesses away from the driven shaft. Rotor angle is reported by resolver feedback (RSF); this analog transducer supplies sine and cosine signals for high-resolution interpolation, supporting the motor’s specified relative position detection. Size code 025 indicates the stator diameter, and length code B adds an intermediate rotor stack that increases torque capability over the shorter A variant without changing the mounting face. By combining these mechanical dimensions with relative feedback and a keyed shaft, the unit fits coordinated multi-axis systems that demand repeatable positioning but limited continuous power.
